From 25b7711be66e289f0f7c9af315d831b2823a51c9 Mon Sep 17 00:00:00 2001 From: ZhangXiaoxu Date: Mon, 19 Aug 2019 11:31:21 +0800 Subject: [PATCH] dm space map metadata: fix missing store of apply_bops() return value In commit 0a16d460d1a8 ("dm space map metadata: fix occasional leak of a metadata block on resize"), we refactor the commit logic to a new function 'apply_bops'. But when that logic was replaced in out() the return value was not stored. This may lead out() returning a wrong value to the caller.
